    wprintf(L"SetProcessWindowStation() before: %x\n", GetProcessWindowStation());
    HWINSTA winSta = CreateWindowStation(_T("hiddenWinSta"), 0, 0, NULL);
     if (winSta == NULL)
     {
        wprintf(L"CreateWindowStation() failed, error %d!\n", GetLastError());
     }else
        wprintf(L"CreateWindowStation() is OK!\n");
    SetProcessWindowStation(winSta);
    OpenDesktop(L"default", 0, FALSE, READ_CONTROL | WRITE_DAC | DESKTOP_WRITEOBJECTS | DESKTOP_READOBJECTS);

Answer 1

Error 5 is ERROR_ACCESS_DENIED

From CreateWindowStation

lpwinsta [in, optional]

The name of the window station to be created. Window station names are case-insensitive and cannot contain backslash characters \. Only members of the Administrators group are allowed to specify a name. If lpwinsta is NULL or an empty string, the system forms a window station name using the logon session identifier for the calling process. To get this name, call the GetUserObjectInformation function.

So either start your program as administator or don't specify a name.
